"Thou Shalt Not Kill:" Theological and Ethical Reflection on the Sanctity of Human Life in Nigerian Society in the Age of Digital Technology

Abstract

Grounded in the doctrine of Imago Dei and the Sixth Commandment, “Thou shalt not kill,” the sanctity of human life is a foundational Christian theological and ethical principle. In contemporary Nigerian society, this principle faces serious challenges as physical violence coexists with the emerging phenomenon of “digital murder,” characterised by online incitement, exposure to graphic content, and the devaluation of life through digital media. Using a mixed-methods approach, this study examined how digital technology reshapes perceptions and treatment of human life in Nigeria by engaging theological foundations and the lived realities of faith communities. Survey data and qualitative insights from 500 Christian participants in South-Western Nigeria revealed a significant ethical contradiction. While most respondents affirmed belief in Imago Dei, many admitted to sharing or consuming violent online content and reported desensitisation to violence through digital media. In addition, a substantial number reported limited exposure to religious teachings and pastoral guidance on digital ethics. This gap between Christian belief and digital practice highlights the urgent need for theological engagement and public ethics education. The study advocates contextualised digital discipleship grounded in virtue ethics and media ecology to affirm the sanctity of life in digital and physical spaces.
